(a) Interpretation: The free radical polymerization of low-density polyethylene (LDPE) is favorable is to be stated using bond dissociation energies. Concept introduction: A process of polymerization in which the growth of chain involves free radicals is known as free radical polymerization. The process includes three steps; the chain initiation step, the chain propagation step and the chain termination step. The minimum amount of energy needed to dissociate a bond is known as the bond dissociation energy (BDE). The term bond dissociation energy is only used for diatomic species.

Answer 1

Question

Formula Formula Bond dissociation energy (BDE) is the energy required to break a bond, making it an endothermic process. BDE is calculated for a particular bond and therefore consists of fragments such as radicals since it undergoes homolytic bond cleavage. For the homolysis of a X-Y molecule, the energy of bond dissociation is calculated as the difference in the total enthalpy of formation for the reactants and products. X-Y → X + Y BDE = Δ H f X + Δ H f Y – Δ H f X-Y where, ΔHf is the heat of formation.
